Determination of liquefaction potential using a static penetration test

In December 2020, the Sisak-Moslavina County was struck by a 6.2 magnitude earthquake on the Richter scale. This earthquake caused liquefaction, a natural phenomenon in saturated granular soils, where sand below the groundwater level temporarily loses its shear strength and behaves like a liquid. The susceptibility of soil to liquefaction is determined through its liquefaction potential. The paper focuses on the area of Milana Makance Street and Slavka Kolara Street, where sand was ejected to the surface, using the results of static penetration tests to determine the liquefaction potential.
